RMI
The RMI is a combined radio tranceiver and
machine interface.
The RMI is designed to be mounted within
the machine's working envelope.
Power supply
The RMI can draw its supply from the CNC
machine 12 V to 30 V d.c. supply and presents a

peak load of up to 250 mA during turn on
(typically 100 mA from 24 V).
Alternatively, power may be supplied from
a Renishaw PSU3 power supply unit.
Input voltage ripple
The input voltage ripple shall not cause the
voltage to fall below 12 V, or rise above 30 V.

RMI visual diagnostics
RMI visual diagnostics
A visual indication of system status is provided by LED's.
Status is continuously updated and indication is provided for
START, LOW BATTERY, PROBE STATUS, ERROR, SIGNAL STRENGTH
LED LIGHT SIGNALS
1. LOW BATTERY
Red Battery is low.
Green M code start/stop in
progress.
Yellow Battery low & M code
start/stop in progress.
Off Battery is O.K. (and no
M code start/stop in
progress).
2. PROBE STATUS
Red Probe triggered or unknown
status.
Green Probe is seated.
KEEP THE
FRONT COVER
CLEAN

3. ERROR
Red Error, other outputs may
be incorrect.
Off No Error.
4. SIGNAL
Green Full signal strength.
Yellow Medium signal strength.
Red Low signal strength, radio
link may fail.
Off No signal detected.
Green/off Flashing: RMI is acquisition
mode, and can acquire a
partner RMP.
Red/yellow Flashing: RMI has (just)
acquired a new partner RMP.
Notes.
1. The probe status LED will always be
illuminated when power is present.
There is no ‘power present’ LED.
2. All the indicators report the status of the
partner RMP. If there is no partner in range,
or the partner is off then the probe status
and error LEDs will be red and the other
LEDs will be off.
3. When the RMI is powered it will enter the
acquire partner mode which will be indicated
by the flashing green signal LED.
After a short time (~12 secs) it will switch to
its normal mode listening for its partner.
4. The conditions shown by the low battery,
probe status and error LEDs are the same
as those present on the electrical signal
outputs.
